| 摘要: |
| 利用显微观察及生物冷冻切片技术,对采集自河北秦皇岛的多管藻类(Polysiphonia Complex)海藻样品进行形态分类学研究。经鉴定,样品中包括:多管藻属(Polysiphonia)2种:多管藻(Polysiphonia senticulosa Harvey)和丛托多管藻(Polysiphonia morrowii Harvey);新管藻属(Neosiphonia)2种:倾伏新管藻(Neosiphonia decumbens(Segi) Kim et Lee)和球果新管藻(Neosiphonia sphaerocarpa(Børgesen) Kim et Lee),其中丛托多管藻、倾伏新管藻及球果新管藻均为渤海西岸首次记录。本文对样品物种的外部形态及内部结构特征进行了详细描述,并提供了清晰的特征图片。研究结果补充了渤海湾内的藻类资源数据,为多管藻类相关研究提供了分类学参考。 |

| Abstract: |
| Through microscopic observation and biological frozen section techniques, the morphological taxonomy of the Polysiphonia Complex collected from Qinhuangdao, Hebei, was studied. The samples were identified as two species of Polysiphonia, namely Polysiphonia senticulosa Harvey and Polysiphonia morrowii Harvey, and two species of Neosiphonia, namely Neosiphonia decumbens (Segi) Kim et Lee and Neosiphonia sphaerocarpa (Børgesen) Kim et Lee. Among them, P. morrowii,N. decumbens, and N. sphaerocarpa were first recorded on the west coast of the Bohai Sea. This paper describes the external morphology and internal structure characteristics of the samples and presents clear pictures describing the features. The research results supplement the data on algae resources in Bohai Bay and provide a taxonomic reference for the related research on the Polysiphonia Complex. |
